This book explores the physical public spaces of communication in East Arabia, known as majālis, as well as the digital cyber spaces that serve as their equivalent. These spaces are where Arabian social groups regularly interact, discuss diverse topics, communicate traditional and modern knowledge, and circulate ideas. The book focuses on how these spaces are used to communicate knowledge, beliefs, attitudes, heritage, ideologies, norms, and values, with Islamic religious ways of thinking being prevalent. The book also examines the micro cultural foundation that regulates the unification or fragmentation dynamics between Sufi and Salafi clusters of contemporary Sunni Islam in Eastern Arabia, highlighting how cognitive identity manifests in the realms of attires, melodies, and digitally-mediated Islam.
